Why do we say IoT requires new thinking about cyber security? Mainly because of the level of data sharing involved. This is a fast-evolving feature of the IoT, around which industrial equipment markets have not yet aligned. Note that we can trace the origins of the IoT to the early efforts by engineers in Original Equipment Manufacturers (OEMs) to find ways to monitor, objectively and in real time, how the machines they designed for customers actually performed in the real word. They tended to use the terms telematics and mobile resource management. Soon, however, it became clear how valuable such data would be to their colleagues in product marketing, and in turn to customer service and technical support. As for the customers themselves, they received some benefits, such as maintenance alerts but, generally speaking, they had access to little real-time data, and it was difficult to work with when they did get it.
Today, growing numbers of customers recognize how that data could inform their own operations, and even feel it is rightfully theirs, leading to battles over who owns and has access to what data, who is responsible for securing it, and a long list of other related questions. What's more, as systems built by different OEMs interact, there is infighting among them as to what constitutes sensitive or competitive intelligence. Simultaneously, everyone must address the question of how shared access to data exposes them to new legal liabilities with their trading partners.
